I currently use a mix of rsync and rdiff-backup to backup my home system.
The basic backup is an rdiff-backup of all of /home to the NAS server in the garage.
*However* (and it's a big however) this has one huge hole in it, rdiff-backup does *not* copy the 'contents' of symbolic links. All it does (if you tell it to) is to copy the symbolic link leaving it on the resulting backup as a symbolic link which points at nothing.
This is all very well if you live in a perfect world where all of your system resides in one neat partition etc. but my home directory has symbolic links to old (and not so old) data on other filesystems and partitions. Thus rdiff-backup doesn't back these up.
I'm looking around for something like rdiff-backup that does incremental backups but *also* copies *everything* that is part of /home/chris whether it's via a symbolic link or not. Can anyone recommend anything?
